Wideband MIMO radar space-time processing with Doppler compensation

With the development of multiple-input multiple-output (MIMO) radar, in addition to satisfy general function in target detection, most systems also involve the function of target recognition, parameter estimation, etc. This requires that the MIMO radar works in wideband mode. This paper proposes a way to detect moving target using Doppler effect correction, while the airborne MIMO radar transmits wideband frequency-division linear frequency modulation (FDLFM) signals. Both moving target detecting (MTD) processing and joint domain localized (JDL) processing are used to verify the proposed method. Simulation results also demonstrate the validity of the method.
